Abstract: 900,734. Continuous casting-machines; curving; straightening. CONCAST A.G. July 29, 1960 [Sept. 1, 1959], No. 26441/60. Classes 83 (1) and 83 (4). An arrangement for feeding in the starting bar in a vertical continuous casting plant comprises holding means for receiving the starting bar with the headpiece as a unit and movable in the longitudinal direction of the vertically descending casting. The receptacle 26, Fig. 1, for the starting bar 27 is vertically reciprocable by a hand winch 34 and is counterweighted by a weight 37 which is heavier than the receptacle 26 alone, but lighter than the receptacle when carrying the starter bar. The winch drive may be disconnected so that the receptacle, after receiving the starter bar and the cutting of the bar from the casting, will move downwards under gravity and open a gap between the starter bar and the casting. The casting is deflected to straightening rolls 22 by a bending roller 15 operated by a cylinder 18. Rodwork 19 is provided with adjustable stroke-limiting means. In a modification, Fig. 3, the casting is divided by a cutter 40 and the sections are received in turn by driven rollers 43 in a device 41 which is tiltable by driving means 49 to discharge the castings horizontally on to a conveyer 50.

Title: Improvements in or relating to apparatus for forming concrete piles
IPC: E02D7/30
Filed: 1923-08-30
Abstract: 228,485. White, A. E., (Raymond Concrete Pile Co.). Aug. 30, 1923. Piles; piles, driving.-Apparatus for forming concrete piles comprises a sheet metal shell, either cylindrical or tapered, corrugated circum. ferentially in screw-thread fashion, and a correspondingly corrugated driving core, the ribs on the core being narrower than the grooves in the shell so as to provide clearance to enable the core to be lifted in the shell to relieve pressure on the latter before unscrewing the core from the shell. The core may also be provided with means for discharging fluid under pressure against the inside of the shell to loosen it. The shell may be made in sections as described in Specification 225,290. The tapered shell 71, Fig. 1, is composed of short lengths, the upper end' of each length being enlarged to permit the lower end of the section above to be screwed into it. A shoe 46 is screwed to the lowest section. The one piece core 72 is tubular and is mounted in head 63 so as to be rotatable bv means of worm gearing 74, 75. The head 73 is prevented from rotating by ears 76 which engage with a fixed part of the pile driver. The core is disengaged from the shell by unscrewing for a few turns, after which it can be lifted out. The hollow core is preferably provided with numerous openings 80 through which air or fluid under pressure can be forced by connecting a source of supply to a nipple 81. To prevent rotation of the shell it may be provided with lateral ears 82. When the core is removed concrete is deposited in the shell to form the pile. The shell is of metal of any suitable gauge, and may be made as described in Specification 225,290. The corru. gations may be of the wave type, preferably about a quarter or five sixteenths of an inch deep and from one inch to one inch and a quarter in pitch. The upstanding corrugations on the core are made narrower than the interior hollows in the shell, so that a slight clearance 115, Fig. 8, is left. The core can then be lifted slightly prior to unscrewing so as to facilitate this operation. The form shown in Fig. 5, in which the lower face 122 of the corrugations is nearly horizontal may be used in some cases. Fig. 6 shows a cylindrical core composed of sections 112 having spigot joints 113 which may be of tapered thread type. This core is screwed into or out of the shell by a tool which engages internal lugs 114. When an open bottomed core is used, the earth inside may be removed by an air jet as described in Specification 225,290. The driving point for such a core may be a short tube 111 of thin metal which will collapse when hard rock is encountered, thus obviating damage to the core and preventing ingress of water.
